# 10 x 10 grid

Investigate further.

The purpose regarding this investigation is in order to prove or disprove of which there is a correlation between the products of nook numbers of any size container within any size grid. I shall calculate the diagonal difference (d) regarding a box. There are really two ways to estimate the difference between typically the products:

Versus

W

Con

Z

i actually. W x Y – V x Z

ii. V by Z – W x Y

I actually shall begin with the 10 x 10 grid, because shown above, and a new 2 x 2 box.

2 times 2 box #1

I have replaced numbers for the characters inside my two formulae.

i. d = 2 x 11 – 1 x 12 sama dengan 22 – 12 = ten

2. d =1 x 13 – 2 x eleven = 12 – 22 = -10

d = +/-10

I will employ formula i, because method ii creates negative numbers, which could make the calculations more complex as compared to necessary.

d = 13 x 22 – 12 x 23

d = 286 – 276

d = 10

I think that will d = 10 for any 2 x a couple of box within a 10 x 10 grid. I will test this theory once again, using the highest figures possible in the main grid, to evaluate that it is usually not a coincidence.

2 x 2 box #3

d = 90 times 99 – 89 x 100

m = 8910 – 8900

d = 10

Algebraic proof: formula #1:

+10

a new

a & 1

a new + 10

a + 10 & 1

m = (a + 1) (a + 10) – a (a + ten + 1)

= a2 + 10a + a + 10 – a2 – 10a – a

= 10

I have noticed that d = 10, and the grid is 12 columns (G) wide. To be able to test if this is a coincidence, I have got amended my formula.

Algebraic proof: formula #2:

+1

+G

a

a + just one

a + G

an and up. G + one

d = (a + 1) (an and up. G) – a (a + G + 1)

= a2 + aG+ a + c – a2 – aG – the

= G, exactly where G = 10, m = 10

I will test method #2 using a two x 2 box upon a different size grid. I will make use of a five x 5 grid.

d = 20 x 24 – 19 x 25

The results present that d = H. I am going to use formula #2 to any extent further.

I shall go back to be able to using a 10 times 10 grid. I should test the formula making use of different sized boxes. We shall draw up the table to record our results. I shall evaluate the outcomes to see in case there is a design forming. This would prove correlation.

NB: To save time We shall only indicate the particular corner numbers in each box. The other numbers inside the box are irrelevant for these calculations.

Algebraic proof:

a + 2G +2

chemical = (a + 2) (a + 2G) – a (a + 2G + 2)

= a2 + 2aG + 2a + 4-G – a2 – 2aG – 2a

= 4G, where Gary the gadget guy = 10, d sama dengan forty

Thus far my theory is correct. I shall keep on to test it upon boxes of increasing found in size. I feel it is just necessary to show one numeric and one algebraic calculation for people boxes.

= 9G, wherever G = 10, m = ninety days

d = (a & 4) (a + 4G) – a (a & 4G + 4)

= a2 and up. 4aG + 4a & 16G – a2 – 4aG – 4a

= 16G, where G = 10, m = 160

The results to date are:

10, 40, 90, 160

At this time there is a pattern, which is easier to recognise in case written:

1 times 1

2 x 2

3 x a few

4 x some

5 x 5

The design shows consecutive square numbers. They are also the particular square of one less than the square sizing (x) that produced them.

So:

d = H (x – 1) two

I have extended the results table and added my predicted results, in red, for the remaining box sizes.

I shall now see if our predicted results are proper by testing three associated with these box sizes.

d = G (x – 1) 2

= 10 (6 – 1) 2

= 10 (5) 2

sama dengan 10 (25)

= two hundred and fifty

d = 6 by 51 – 1 by 56

d = 306 – 56

d = 250

= 490

d = 8 x 71 – 1 x 78

d = 568 – 80

d = 490

10 x ten box #1

d = G (x – 1) 2

= 10 (10 – 1) 2

= 10 (81)

= 810

d = 10 times 91 – 1 by 100

deb = 910 – one hundred

d sama dengan 810

Typically the tests proved my concept correct. I conclude that this investigation has proved that there is connection between square boxes upon a grid. The master formula is:

d = G (x – 1) 2

To look at further We need to change one of the variables.

5. Grid size, from 12 x 10, to electronic. g. 5 x a few, 7 x 7, nine x 9.

* Shape, from a new square, to e. h. a rectangle, a combination, a T-shape.

I possess chosen to check out rectangle boxes on a 10 x 10 grid. I think that right now there will be a master formula regarding any size rectangle within any size grid. I think that it may be more complex because I will have to take into account the reality that a rectangle offers sides of differing plans, opposed to a sq . having sides all the particular same length.

Rectangles can be used two ways:

Rectangle 2

Rectangle 1

I will call rectangle just one a 4 x 2 ( 4 columns by 2 rows) and rectangular shape 2 a 2 times 4 ( 2 columns by 4 rows).

There are several different possible sizes of rectangle within a ten x 10 grid:

2 x 10

2 x nine

a couple of x 8

2 x 7

2 x 6

2 by five

two x 4

2 x 3

3 x 12

3 x nine

3 x 8

3 x 7

3 x six

3 times five

3 x 4

4 x 10

4 x nine

4 by eight

some x 7

4 x 6

4 x a few

5 times ten

5 x 9

5 x 8

5 x seven

5 times six

six x 10

6 x 9

6 x eight

6 times 7

several x 10

7 x 9

7 x 7

8 x ten

7 x 9

9 x 10

This list exhibits 36 possible sizes. If the orientation of the particular rectangle produces a different value for d, and then there will be seventy two possible sizes.

My first task is to ascertain if the orientation of the rectangle impacts the diagonal difference.
